[PATCH] ARM: dma-mapping: highbank: Restrict DMA to 32-bit addresses

Some devices on Calxeda ECX-2000 are restricted to 32-bit DMA. Thus the platform needs to set dma_zone_size, otherwise dma-mapping code is complaining, e.g. calxedaxgmac fff5.ethernet: coherent DMA mask 0x is smaller than system GFP_DMA mask 0x Same is true
